Figure 1-1  Error reports of disk PHY#23
Alarm Information
None
Handling Process
    Step 1     Replace the faulty disks (the hard disk in Slot#23). For details on the replacement, see Replacing a Disk Module in Oceanspace T3000 Storage Node Troubleshooting-(V100R001C01). For details on the corresponding relationship between the Slot Number and the T3500 slot number, see 3.5 Corresponding Relationships Between PHY Numbers or Slot Numbers and T3500 Slot Numbers in the RAID Card Log.

l  In the versions of T3000 V100R001C01SPC005 and T3000 V100R001C01SPC006, hard disks are arranged in the sequence of slot (1 to 24) in the RAID card logs. For details, see 3.5 Corresponding Relationships Between PHY Numbers or Slot Numbers and T3500 Slot Numbers in the RAID Card Log.

l  In the version of T3000 V100R001C01SPC004 or earlier, hard disks are arranged in the sequence of PHY (0 to 23) in the RAID card logs. For details, see 3.5 Corresponding Relationships Between PHY Numbers or Slot Numbers and T3500 Slot Numbers in the RAID Card Log.                             
Step 2    
Set the new hard disk to a hot spare disk in the RAID group where the new hard disk belongs to if there is no hot spare disk in the RAID group.

Any free disk that is not part of a RAID set can be designated as a hot spare disk.
1.         Starting the McBIOS RAID manager. For details, see 3.7 Starting the McBIOS RAID Manager.
2.         Creating a hot spare disk. You can create the hot spare disk through either of the following two methods:

       Add the hot spare disk through the Quick Volume/Raid Setup function, and the McBIOS RAID manager will automatically display the available RAID levels for users' selection.

       Create the hot spare disk through Create Hot Spare in Raid Set Function. When you create the hot spare disk through this method, all free physical disks connected to the current RAID card are shown on the interface.

----End

Root Cause
According to the error report in the RAID card log, you can determine that hard disks in Slot#23 are faulty. The hard disk that reports Writing Error need to be replaced.
 
Suggestions
Wait for three minutes after the hard disk is inserted and then check the disk online status indicator to determine whether the hard disk is normal.
